@batiibweimran21 there is not enough detail here for a specific answer. Let us know what it is actually doing. You plug your AC adapter in and we need to know if your Laptop has any sign of life. Check to see if any of the LED's is coming on.
Next you want to check your power supply. Make sure it has the proper voltages. Check to make sure that connectors are not bend etc. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. Clean it of any debris etc, use a few puffs of air to clean it out. If none of this works, get a ammeter and see if your laptop draws any amperage from the charger. After that, you need to check and see if your motherboard even gets power. For that of course, you need to open it up. Post Some good pictures of what you see. That way we can see what you see.

What is happening when you plug in the computer? Do any lights show up? Does a fan spin? Does it beep?
